JP 2000-141927 A (published on May 23, 2000)

  In the technique described in Patent Document 1, since the transfer is performed by scanning with a laser, the laser irradiated portion is adhered. However, depending on the laser irradiation method, the transfer state of the boundary portion of the image may be deteriorated, and the image may not be peeled off as intended. Therefore, there is a problem when a high-definition transfer image is required.

  The present invention has been made in view of such problems, and it is an object of the present invention to provide a transfer method capable of obtaining a transfer image with higher definition.

In the transfer method according to the present invention, a laminate in which a transfer layer to be transferred to a transfer target and an adhesive layer composed of an adhesive that is dissolved by heat is stacked, so that the adhesive layer is in contact with the transfer target. Laminating step for laminating on the transfer object, and irradiating the transfer layer and the adhesive layer with laser light from the surface of the transfer layer opposite to the surface on which the adhesive layer is present. A laser beam irradiation process for transferring to the transfer object, and in the laser beam irradiation process, the intensity of the laser beam irradiated to the edge of the area to be transferred is stronger than the intensity of the laser beam irradiated to the inside of the edge. In addition, the laser light irradiation step is characterized in that there is a gap between which the laser beam is not irradiated between the edge portion and the inside where the laser beam having a weaker intensity than the edge portion is irradiated .

By making the transfer layer strong adhesive strength at the edge of the transfer region so that the transfer layer can be broken, the transfer layer can be broken into the intended shape, and the intended transfer image can be made high definition. That is, if the adhesive strength is insufficient or the strength distribution is not uniform, the transfer layer may not be broken as intended. However, by increasing the intensity of the laser light applied to the edge of the transfer area from the inside, the amount of heat applied to the adhesive layer is increased, and at least one of the adhesive layer and the transfer layer is cut at the edge. Thus, the transfer layer is easily broken at the boundary between the outer side and the inner side of the edge. Therefore, a higher definition transfer image can be obtained. Here, since the adhesive layer is heated by the laser beam, there is a possibility that the peripheral region of the region irradiated with the laser beam with a strong intensity may be bonded with a strong strength by the heat transfer. If this happens, the transfer layer may be broken as intended. Therefore, by providing the gap, it is possible to suppress the amount of heat applied to the peripheral region of the adhesive layer and eliminate such a concern.

  In the transfer method according to the present invention, it is more preferable that the groove is formed in the transfer layer by irradiating the edge with a laser in the laser light irradiation step.

  When irradiating the edge with a laser beam having a high intensity, the edge of the transfer layer is easily broken by forming a groove in the transfer layer (previously cut in a half-cut state).

  In the transfer method according to the present invention, in the laser light irradiation step, it is more preferable that the transfer layer is cut along the edge by irradiating the edge with a laser.

  By irradiating with a laser beam having a strong intensity sufficient to cut the transfer layer, it is not necessary to break the transfer layer later, and a high-definition transfer image can be obtained more easily.

  In the transfer method according to the present invention, in the laser light irradiation step, it is more preferable to dispose the laminated body in a housing and discharge gas from the housing to the outside of the housing.

  By adsorbing the transferred body and the laminated body, it is possible to irradiate the laser beam while preventing the positional deviation between the transferred body and the laminated body.

The transfer device according to the present invention includes a laminate in which a transfer layer and an adhesive layer to be transferred to a transfer body are laminated to the transfer target so that the adhesive layer adheres to the transfer target. Laser light irradiation for transferring the transfer layer to the transfer object by irradiating the transfer layer and the adhesive layer with a laser beam from the surface of the transfer layer opposite to the surface on which the adhesive layer is present comprising a part, the intensity of the laser beam irradiated to the edge of the area to be transferred, and the laser beam intensity control means for controlling so as to increase than the intensity of the laser beam irradiated to the inside of the edge portion, the laser beam The irradiating unit irradiates the laser beam so as to provide a gap that does not irradiate the laser beam between the edge and the inside that irradiates the laser beam having a weaker intensity than the edge .

Since the transfer method according to the present invention can be suitably performed, a transfer image with higher definition can be obtained. Here, since the adhesive layer is heated by the laser beam, there is a possibility that the peripheral region of the region irradiated with the laser beam with a strong intensity may be bonded with a strong strength by the heat transfer. If this happens, the transfer layer may be broken as intended. Therefore, by providing the gap, it is possible to suppress the amount of heat applied to the peripheral region of the adhesive layer and eliminate such a concern.

  The transfer apparatus according to the present invention further includes a housing for enclosing the laminate bonded to the transfer target body, and a gas discharge unit for discharging gas from the housing to the outside of the housing. It is more preferable.

  By adsorbing the transferred body and the laminated body, it is possible to irradiate the laser beam while preventing the positional deviation between the transferred body and the laminated body.

  According to the present invention, there is an effect that a transfer image with higher definition can be obtained.

It is a figure which shows the structure of one Embodiment of the laminated body used with the transfer method which concerns on this invention. It is a figure which shows the intensity | strength etc. of the laser beam irradiated to a laminated body in the transfer method which concerns on this invention. It is a figure which shows the structure of one Embodiment of the transfer apparatus which concerns on this invention.

  Hereinafter, embodiments of the present invention will be described in detail.

<Transfer Method According to the Present Invention>
In the transfer method according to the present invention, a laminate in which a transfer layer to be transferred to a transfer target and an adhesive layer composed of an adhesive that is dissolved by heat is stacked, so that the adhesive layer is in contact with the transfer target. Lamination process for laminating on the transfer target, and laser light irradiation for transferring the transfer layer to the transfer target by irradiating the transfer layer and the adhesive layer with laser light from the opposite side of the adhesive layer In the laser light irradiation step, the intensity of the laser light applied to the edge of the region to be transferred is made stronger than the intensity of the laser light applied to the inside of the edge. By making the intensity of the laser light applied to the edge of the region to be transferred stronger than the inside thereof, the amount of heat given to the adhesive layer can be increased, and higher adhesive strength can be obtained at the edge. Thereby, the transfer layer is easily broken at the boundary between the outer side and the inner side of the edge. Therefore, a higher definition transfer image can be obtained.

[Laminate]
First, the structure of the laminated body used with the transfer method according to the present invention will be described.

  The laminate used in the transfer method according to the present invention is obtained by laminating a transfer layer including a transfer region to be transferred to a transfer target and an adhesive layer composed of an adhesive that is dissolved by heat.

  The transfer layer is composed of a material to be transferred to a transfer target. Examples of the material to be transferred to the transfer target include a metallic layer, a hologram layer, and a color printing layer that cover the transfer target.

  The adhesive layer is composed of an adhesive that dissolves by heat. It absorbs and dissolves the heat generated by the irradiation of the laser beam, and bonds the transfer layer and the transfer target. Since the bonding is not performed in the region not irradiated with the laser beam, the transfer layer is broken along the edge irradiated with the laser beam, and only the transfer layer in the region irradiated with the laser beam remains on the transfer target. Thereby, a transfer image is formed.

  Examples of the adhesive that dissolves by heat include hot-melt adhesives such as paraffin wax, polyethylene wax, polypropylene wax, and polyalphaolefin wax.

  Next, in order to describe the laminate used in the transfer method according to the present invention in more detail, the laminate 10 as an embodiment thereof will be described. FIG. 1 is a diagram showing a configuration of a laminate 10 which is an embodiment of a laminate used in the transfer method according to the present invention.

  The laminate 10 includes a substrate 11, a laser light absorption layer 12, a release layer 13, a metallic layer (transfer layer) 14, and a hot melt adhesive layer (adhesive layer) 15.

  The base material 11 serves as a base for forming other layers such as the metallic layer 14. A specific configuration may be any as long as it transmits the laser beam irradiated in the laser beam irradiation step. For example, a film, a sheet, etc. which transmit a laser beam are mentioned.

  The laser light absorption layer 12 is a layer that generates heat by absorbing the laser light transmitted through the base material. The laser light absorption layer 12 is constituted by, for example, a resin coat layer to which carbon powder, metal oxide, laser light absorption dye, or the like is added. Whether or not the laser light absorption layer 12 is provided may be determined as appropriate from the properties of the metallic layer 14 and the hot-melt adhesive layer 15, and is not an essential configuration.

  The release layer 13 is a layer for peeling the base material 11 and the laser light absorption layer 12 provided as necessary from the metallic layer 14 and the hot-melt adhesive layer 15.

  The metallic layer 14 and the hot melt adhesive layer 15 in the region irradiated with the laser light in the laser light irradiation step remain on the transfer target body, and the base material 11 and the hot melt adhesive layer 15 in the region The laser light absorption layer 12 is peeled off. At this time, the metallic layer 14 and the hot-melt adhesive layer 15 in the region not irradiated with the laser light do not adhere to the transfer target and do not peel from the substrate 11 and the laser light absorption layer 12.

  The release layer 13 is formed, for example, by coating the base material 11 or the laser light absorption layer 12 with a silicone resin.

  The metallic layer 14 is an example of a transfer layer of a laminate used in the transfer method according to the present invention. In the present embodiment, by transferring a desired region of the metallic layer 14 onto the transfer target, the surface of the region can be given a metal-like texture.

  The specific structure of the metallic layer 14 is a metal thin film such as a deposited film of aluminum, gold, silver, nickel or the like, an aluminum foil, or a metal film formed by electroless plating.

  The hot melt adhesive layer 15 is an example of an adhesive layer of a laminate used in the transfer method according to the present invention. The heat generated by the irradiation with the laser light is absorbed and dissolved, and the metallic layer 14 and the transfer target are bonded.

  The method for forming the laser light absorbing layer 12, the release layer 13, the metallic layer 14, and the hot melt adhesive layer 15 on the substrate 11 is not particularly limited, and the respective materials are formed by a conventionally known coating method or the like. What is necessary is just to apply | coat etc.

[Lamination process]
In the laminating step of the transfer method according to the present invention, a laminate in which a transfer layer and an adhesive layer are laminated may be laminated on a transfer target body so that the adhesive layer is in contact with the transfer target body. At this time, the adhesive layer remains hardened, and the laminated body and the transfer target are not bonded, so it is only necessary to superimpose them.

[Laser irradiation process]
In the laser light irradiation step of the transfer method according to the present invention, the transfer layer and the adhesive layer are irradiated to the transfer layer by irradiating the transfer layer and the adhesive layer with laser light from the surface opposite to the surface having the adhesive layer. In this transfer step, the intensity of the laser beam applied to the edge of the transfer area is made stronger than the intensity of the laser beam applied to the inside of the edge.

  For example, the region to be transferred may be irradiated while being scanned with laser light, and the intensity of the laser light may be increased or the irradiation time may be lengthened when scanning the edge. Further, the laser beam diameter may be reduced when scanning the edge. By reducing the beam diameter, it is possible to locally irradiate a laser beam with a stronger intensity in a shorter time, and a higher-definition transfer image can be obtained.

  The intensity of the laser may be appropriately set depending on the quality of the base material, the transfer layer, and the adhesive layer, but for example, the edge is capable of cutting the transfer layer and the adhesive layer, and the inside is a portion irradiated with the laser. It is good for the intensity | strength to become 70 to 250 degreeC which the hot-melt-adhesion layer 15 fuses.

  In the laser light irradiation step, it is more preferable to form grooves in the transfer layer by irradiating the edge with laser.

When a strong laser beam is irradiated on the edge portion, the transfer layer is easily broken by forming a groove in the transfer layer. The grooves are preferably formed with a uniform depth, but the grooves may be formed intermittently or the depth of the grooves may be changed within a range that does not affect the accuracy of the transferred image.

  In the laser light irradiation step, the transfer layer may be cut along the edge by irradiating the edge with laser.

  By irradiating with a laser beam having a strong intensity sufficient to cut the transfer layer, it is not necessary to break the transfer layer later, and a high-definition transfer image can be obtained more easily.

  In the laser light irradiation step, it is more preferable to provide a gap that does not irradiate the laser light between the edge and the inside where the laser light having a weaker intensity than the edge is irradiated.

  Since the adhesive layer is heated by the laser light, there is a possibility that the peripheral region of the region irradiated with the laser light with a weak intensity may be bonded by heat transfer. If this happens, the transfer layer may be broken as intended. Therefore, in anticipation of the adhesion area that expands due to heat transfer, after irradiating laser light with weak intensity in a range smaller than the intended transfer area, the above gap is provided, and a strong intensity laser is applied to the edge of the intended transfer area. It is good to irradiate light. Even if the adhesion area is enlarged by heat transfer, transfer can be performed in the intended transfer area.

  In the laser light irradiation step, it is more preferable to dispose the laminated body in the housing and discharge gas from the housing to the outside of the housing.

  The transferred object and the laminated body after the laminating process and before the laser light irradiation process are simply overlapped and not bonded. Therefore, there is a possibility that the position of the transferred body and the laminated body may be shifted during the laser light irradiation process. However, the laminated body and the transferred body are adsorbed by removing the gas from the housing and placing the transferred body and the stacked body in a low pressure, preferably in a vacuum environment. Thereby, it is possible to irradiate the laser beam while preventing the positional deviation between the transfer target and the laminate.

  Next, an example of a laser irradiation process will be described with reference to FIG. 2A and 2B are diagrams showing the intensity of the laser beam irradiated to the laminate, and FIG. 2A is a view of the transfer region from above, and FIG. 2B is a transfer layer ( It is sectional drawing of a metallic layer 14) and an adhesive layer (hot-melt-adhesive layer 15).

  As shown in FIGS. 2A and 2B, the edge portion 14a is irradiated with laser light having a stronger intensity than the inside 14c. A gap 14b is provided between the edge 14a and the inside 14c, and no laser light is irradiated onto the gap 14b.

  Further, the width of the gap 14b is set to a width through which heat generated by the laser light applied to the edge portion 14a is transmitted.

  As shown in FIG. 2 (b), in the hot melt adhesive layer 15, the adhesive layer internal region 15a corresponding to the region below the internal 14c is melted by the laser light applied to the internal 14c, and the transfer target underneath is transferred. The body and the metallic layer 14 are bonded.

Further, the adhesive layer outer region 15b under the edge 14a and the gap 14b is melted by receiving the heat transfer of the weak laser beam applied to the inner portion 14c, and has substantially the same strength as the adhesive layer inner region 15a. Then, the transfer object and the metallic layer 14 are bonded. As a result, the edge 14a and the gap 14b of the transfer region are bonded to the transfer target with substantially the same strength as the inside 14c. Then, the edge portion 14a is irradiated with a strong laser beam to cut the edge portion 14a. Since the boundary of the bonded area and the edge portion 14a overlap, the transfer area easily breaks at the boundary between the outer side and the inner side. Therefore, a high-definition transfer image can be obtained. When the base material 11 is peeled after the metallic layer 14 is broken (cut), the non-transfer area is usually peeled together. However, when the base material 11 is also burned out, it is preferable to peel off the base material 11 in the non-transfer area remaining on the transfer target 20 using an adhesive sheet or the like.

<Transfer device according to the present invention>

  The laser light intensity control unit 3 is for controlling the intensity of the laser light emitted from the laser light irradiation unit 2, and the intensity of the laser light applied to the edge of the region to be transferred on the laminate 10 is set to the edge. Control is performed so that the intensity is higher than the intensity of the laser beam applied to the inside of the unit.

  An example of the control flow of the laser light intensity control unit 3 is as follows.

  For example, the laser light intensity control unit 3 first receives data indicating an area (transfer area) to be irradiated with laser light by a user input or the like.

  Next, based on the data, the laser light intensity control unit 3 drives the driving unit to scan the laser light irradiation unit 2. The driving means may be driven by a control means other than the laser light intensity control unit 3.

  Next, for example, when irradiating laser light to a region corresponding to one dot, which is the edge of the data, the laser light intensity control unit 3 increases the intensity of the laser light, lengthens the irradiation time, The diameter is reduced, and control is performed so that the intensity of the laser beam irradiated onto the laminate 10 is increased. As described above, the intensity of the laser beam applied to the edge is controlled by the laser beam intensity controller 3.

  The film container 4 is for storing the laminate 10 and the transfer target 20. The laminated body 10 and the transfer target 20 are placed in the film container 4 so that the side on which the laminated body 10 is located is positioned on the side where the laser light is irradiated by the laser light irradiation unit 2. Can be suitably performed.

In the laser light irradiation step, air in the film container 4 is discharged out of the film container 4 by a gas discharge unit 5 described later. At this time, the film container 4 is discharged as the air is discharged. 3 contracts like a film container 4 ′ indicated by a broken line. Thereby, the laminated body 1
0 and the transfer target 20 are in close contact with each other.

  The material of the film which comprises the film container 4 should just be a thing which permeate | transmits a laser beam.

  The gas discharge part 5 is for discharging the gas in the film container 4 out of the film container 4. For example, a suction pump or the like may be used. By setting the inside of the film container 4 to a low pressure or vacuum environment by the gas discharge unit 5, the stacked body 10 and the transfer target 20 can be adsorbed to prevent misalignment.

  The present invention is not limited to the above-described embodiment, and various modifications are possible within the scope shown in the claims, and the embodiment is obtained by appropriately combining the technical means disclosed in the above-described embodiment.
